Exemplary embodiments of the present application will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 3, a vehicle according to an aspect of the present application may include various displays 100, and a glass plate 10 is disposed at a front side of the displays 100. Here, the glass plate 10 may form a front surface of the display 100, or may be formed separately from the display 100. In addition, the glass plate 10 may be disposed separately from the display 100.

On the front side of the glass plate 10, an antireflection film 20 for preventing a ghost image problem is disposed. The anti-reflection film 20 may be attached to the front surface of the glass plate 10.

The antireflection film 20 may include a plurality of partition walls 23, a front film 22, and a rear film 21; the plurality of partition walls 23 are disposed in parallel and spaced apart from each other, the front film 22 is disposed to cover the front side of the partition wall 23 where the driver is located, and the rear film 21 is disposed to cover the rear side of the partition wall 23 where the display 100 is placed.

The partition wall 23 may be transitioned between the transparent state and the black state to selectively suppress the ghost problem due to external illumination.

The partition wall 23 may be formed of a hollow transparent pipe so that the partition wall 23 can be transitioned between a transparent state and a black state.

The vehicle may further include a transparent fluid supply 24, a black fluid supply 25, a controller 30, and an illumination detection sensor 40; the transparent fluid supply device 24 is for supplying transparent fluid to the partition wall 23, the black fluid supply device 25 is for supplying black fluid to the partition wall 23, the controller 30 is for controlling the operations of the transparent fluid supply device 24 and the black fluid supply device 25, and the illumination detection sensor 40 is for detecting illumination outside the vehicle.

In the case of a vehicle operating at low temperatures (e.g., in winter), the clear fluid and the black fluid may be made of an antifreeze liquid.

The partition walls 23 may be vertically spaced apart from each other, and may be formed to have a cross section whose vertical direction length narrows from the rear side where the display 100 is placed to the front side where the driver is located.

Here, the partition walls 23 may be vertically spaced apart. However, the partition walls 23 may be spaced apart from each other in the left-right direction, and the partition walls 23 may be vertically and horizontally spaced apart to form a mesh shape.

A method of controlling the vehicle will be described below.

The ghost image problem of a vehicle does not generally occur during the day when the illumination outside the vehicle is high, but mainly occurs during the night when the illumination outside the vehicle is low.

Therefore, the illumination detection sensor 40 can recognize illumination outside the vehicle.

When the illumination outside the vehicle detected by the illumination detection sensor 40 is equal to or higher than a predetermined level, the controller 30 may operate the transparent fluid supply device 24 to supply the transparent fluid to the partition wall 23. Therefore, when the transparent fluid supply device 24 supplies the transparent fluid, the black fluid may flow back (receiver) to the black fluid supply device 25.

When the transparent fluid is supplied to the partition wall 23, the partition wall 23 may be transformed into a transparent state.

When the partition wall 23 is in the transparent state, the light generated by the display 100 and passing through the glass plate 10 may be directly transmitted to the driver, thereby enabling the driver to easily recognize the information displayed on the display 100. At this time, a portion of the light generated by the display 100 may be irradiated through the windshield of the vehicle, but is inconspicuous compared to the amount of light supplied from the outside of the vehicle through the windshield, and thus cannot be recognized by the driver.

In contrast, when the illumination outside the vehicle detected by the illumination detection sensor 40 is lower than a predetermined level, the controller 30 may operate the black fluid supply device 25 to supply the black fluid to the partition wall 23. Therefore, when the black fluid supply device 25 supplies the black fluid, the transparent fluid may flow back to the transparent fluid supply device 24.

When the black fluid is supplied to the partition wall 23, the partition wall 23 may transit to a black state as shown in fig. 2 and 4.

When the partition wall 23 is in the black state, among the light traveling through the glass plate 10, the light generated by the display and irradiated to the driver may pass through the antireflection film 20 and may travel directly to the driver. Light irradiated toward the windshield at the front of the vehicle may be absorbed by the partition wall 23 that is almost black.

Therefore, the ghost problem generated when light generated by the display 100 is irradiated to the windshield at the front of the vehicle can be suppressed.

At this time, a part of light generated by the display 100 is partially absorbed by the partition wall 23, and thus illumination of the display 100 is reduced. However, since the illumination outside the vehicle is very low, even if a part of the light generated by the display 100 is absorbed by the partition wall 23 in the black state, the driver can easily recognize the information displayed on the display 100 due to the dark adaptation.

As is apparent from the above description, the vehicle according to the embodiment can effectively suppress the occurrence of ghost images on the windshield of the vehicle, since the partition wall of the antireflection film is turned into the transparent state and the black state.

Although exemplary embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention. Accordingly, the exemplary embodiments of the present application are not described for limiting purposes.
